  * --NORMAL IS 4.7kohm PULLUP!-- 1kohm pullup can be used on hotend sensor, using correct resistor and table

  *    60 : 100k Maker's Tool Works Kapton Bed Thermistor beta=3950

  *       1k ohm pullup tables - This is atypical, and requires changing out the 4.7k pullup for 1k.
  *                              (but gives greater accuracy and more stable PID)
